Frequently Asked Questions
The most recent CBSE syllabus states that the main subjects covered are the discovery of electrons, protons, neutrons, and other elements, as well as atomic models (such as Thomson, Rutherford, and Bohr models). The above article provides a complete list of subtopics covered.
Bohr’s model explains the stability of atoms. It introduces the idea of electrons moving in fixed orbits around the nucleus and quantifies their energy levels. This helps in understanding the arrangement of electrons in an atom.
These solutions make the concepts very easy to understand. The detailed explanation helps students understand the concepts and prepare for the test easily.
